Re: [Perc] Signaling the SDP dtls-id in DTLS

["Paul E. Jones" <[e-mail]>]

Martin,

I have no particular desire to see dtls-id in DTLS standardized in PERC, 
though I did want to have a discussion to see if we can take this 
approach to solve one of the open issues with the PERC tunnel spec.  If 
there is agreement on the approach, let's definitely figure out how to 
get it done.

The procedural bits in the draft Nils and I submitted should be 
integrated into other PERC documents (e.g., tunnel and some other 
document for the endpoint procedures).  We did not intend for that draft 
to continue going forward, but just to serve as a starting point for 
discussion on this approach.

Paul
